The present invention relates to an'attachment for cultivators and'has for its object to 7 provide a comparatively simple andinexpensiVe device by means of which the ordinary '5 Wheeledcultivator may be readilyconverted into alister corn cultivator or go-devil; there: by avoiding the using of two machines',one for listing crops and-the other, for ordinary crops. More specifically -my invention 'jcontemplates the construction of "an attachment which may be securedL to the lower endfof a shank by a split sleeve haying adjustable means associated therewith for disk cultivat- A still further very important object of the invention resides in the provision ofan attachment of this'nature which may be easily and quickly installed, strong and durable in construction, easy toiasse'mbleanddisassem ble, thoroughly efiicient and reliable in use, and otherwise well adapted to the purpose for which itis designed. t i V I With thejabove and numerous'otherob ects in View as will appear as the description proceeds,rthe invention resides in certain novel features oftconstruction', and inthe comb-ination'and arrangement ofparts as will 1 be hereinafter more fully described and claimed. v

In the drawing: r V Figure 1 is a perspectiveview ofa'cultivator frame showing my attachments thereon, Figure 2 is .a rearelevation of one of the attachments, one of the ends" being removed, Figure 3 isa-front elevation thereof, Figure 4: is a top plan View thereof, Figure 5 is asectional View taken substa t-ially on the line 5-5 of Figure 4:,

Fi ure 6 is a, perspective view 0 the disks, V Figure 7 is a-perspective view and r Figure 8 is a perspective View of a hub; '45 Referring to the drawing in detail, it will i be seen that the numeral 5 denotes a downs wardly turned shank on the lower end of which may be'placed my attachment. Re-

of a bushing,

; ferring especially to one of my attachments it will be seen that the numeral 6 denotes an f one of el ga d split sl eve-wane disk-7 formed "thereon? The split sleeve' is providedf with upper and lower pairs-offapertured ears '8- "through which "are eXtended b'61ts 9 in order thatthe' sleeveimay'be tightened cir'cuinjaceiit I I the lowerend of the shank'5 [A tubular hoii "ing' 10 has-a disk 'llformed thereon a nd p l- V vide'd with: concentrically dis osed slot to receiveboltsel lffroin the di's'k i these "disks may be bolted "together i *ent adj usted position "that" F is l to var i angleof the tubular housing; 10 n respect-to the's'p'lit'sleev itli A 'b'ushing'lfi is rotatab the-ends ofthe'housing-10 and on theinner head '20 with pins 21 pro-j ecting therefromi, i 7 Disks of conca-vo-convex' formation aredc- 1;

T From the abovedetailed descriptiona beseen that 'I provideqafstructure in natureqof an attachment which may; bezrad ilyf'a'ssembled asto itsvaribug' parts and may be readily attached to and/ detached from I I the shank 5. 'i i will clearly understood by thoseskilled in this art without a more detailed description thereof.

Thejpresent embodiment of the invention,

.- has been disclosed in considerable detail95' I of advantage enumerated'as' desirable in the statement of the 1 I invention and the above descriptiom I V. f. I

v magma-abusi g i0... i r and at each endisiprovided w ith a pairtf a5 lugs 17. A pair'o'f hub's lsa ereceiva i cz the 1851 It .is thought that the construction,iutility and advantages of the invention may be now;-,:; 1

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be'resorted-to Without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any, of its advantages.

Having thus described my invention, what I claim as new is: Y

1. In an attachment of the class'described comprising a split sleeve, a disk formedion" the'split sleeve, a tubular housing, a disk formed on the tubular housing, pin and slot means for adjustably securing the disks to-- gether, a bushing rotatable in the housing, hubs connected to the bushing and roatable in the housing, disks, and means for fastening the disks on the hubs.

2. In an attachment of the class described comprising a split sleeve, a disk formed on thesplit sleeve, a tubular housing, a disk formed on the tubular housing, pinand slot means for adjustably securing the disks tor gether, a bushing rotatablein the housing,

.hub s connected to the bushing and rotatable in the housing, disks, and means for fastening 'th'edisks on the hubs, said last mentioned means comprising a shaft with a head at one n 'end,'said shaft extending through the disk, thehubs and'the bushingv and a nut threaded on the other end of the shaft.

3. In an attachment of the class described comprising a'split sleeve, means for clamping the sleeve on a shank, a disk formed on the split sleeve, a tubular housing, a disk formed onthe tubularfhousing, one of said disks 1 having arcuate slots concentric therein, bolts extending from the other disks through the large, pins projecting outwardly from the enlarged'ends, disks having openings to receive the ends, ashaft extending through the cen- I ters, of the disks, through the hubs and bushrin and having aheadat one end and a nut V a at the other end.
